Fixed my Lipos today.

I picked up my Revo used. It had a pair of 3s lipos with it, but the balance plugs had broken wires. My charger didn't want anything to do with them. I bought a pair of new 2s and have been running them (plenty of power). But I got brave and opened the 3s's up today. After getting in there, I stripped the little wires and soldered them back onto the batt terminals. Pretty simple but it was a lil nerve racking at 1st. I charged them up and they work great again. http://i177.photobucket.com/albums/w...1-12125404.jpg

By the way, I'm Robb. Years ago(like 20), I raced all over the state of MI. I was never a great driver but I had a ton of fun. Then kids came along and I put my toys away. Then about a year ago a friend of mine kept buggin me to pull out my old truck. Well I finally did about a month and a half ago. Not long after that, it got upgraded to BL and then Lipos. WOW! What a game changer those two were for the RC world! Ok, so then I decided I was going to buy a Slash 4x4. I started looking on CL and ran across a great deal on a Mamba Revo. It was all jacked up, with a Raptor body on it. It was really hard to keep on its wheels. I took the long travel stuff off and put a Revo body back on it. I have several parts ordered for it so far. I have to say it is a fun beast! I still may buy a Slash 4x4, but the Revo is SIK FUN!!

Welcome & good choice of trucks, unless you just want a different truck. Get another Revo, then you don't need so many different spare parts.......Could build a Slayer instead.....my next truck if I ever get this one built....

I am debating on putting the true-track rear on because I have steel axles already. I just ordered a swaybar kit and new wheels & tires. I will probably upgrade the diffs, but not until I have an issue with the stockers. I never seem to be able to leave my stuff alone, so who knows what else.

Just outta curiosity, were the wires themselves broken, or did the solder points fail? The reason I ask is i'm having the same problem. When charging one of my 3s batteries, the charger shows cell connect error. I resoldered every wire to the battery, and still get the error message. I'm thinking one of the balance wires is broken inside the wire casing. Gonna steal a balance connector off a set of hardcase charge leads I dont use.

My swaybar kit came today. I got them installed and what a difference! I almost can't see why the BL revo doesn't come with them. When I took it out to test it with 6s, it doesn't seem so insanely fast. It still is, but it handles so much better and is much more controllable. That, and my new taped badlands make it a whole different animal. Now I am going to gather my parts to do my single servo conv.

The weather finally got decent enough to take my rev out and check out my single servo set up. So far so good! No BEC, and it worked flawlessly. I ordered a glitch buster but its not here yet. I may not even need that. I am really happy with my HW ESC. I was only out for about 10min before I broke a knuckle, so I didn't get to do a full run with it.

The reason 50 is telling you about the external BEC is two fold and one doesnt apply since you dont run a castle ESC.
The Savox servos are extremely power hungry and cause a lot of problems dragging down the control voltage for the entire truck. Ive seen folks have issues even with non castle ESCs. One big one are those running spektrum RXs, they are extremely picky and will undervolt quickly. Watched a guy with a similar setup running a spektrum RX cream his machine into a concrete rataining wall at high speed when he went to do a sharp turn under full power. The truck just shut down with a total loss of power which meant no drag brake, NADA. Later it was found that his RX was blacking out because the Savox servo was dragging the BEC voltage too low and the RX shut down. There are several work arounds with trying glitch busters or external BECs but IMO the best fix is to choose any servo but Savox. Folks run Hitech servos on a castle ESC with no BEC and spektrum RXs and dont have issues.

So, last time I took my revo out I busted the left rear knuckle about 10min into the run. I didnt have any replacements, so I ordered new ones. I put a new one on, took my revo out and about 10min into my run I broke the left rear knuckle again! Are you guys runnin aluminum ones? Or is there a stronger option?
